Abstract
It is demonstrated that a specially designed wall-stabilised arc combined with a Michelson interferometer and a stigmatic spectrograph is suitable for hook measurements. For a first test of the system relative f values of 24 resonance lines of Ti I have been determined and converted to an absolute scale by means of literature data. The results are in agreement to within better than 25% with published data which were obtained by entirely different methods.
